Has anybody tried to buy a Sam's gift card in warehouse with the Freedom? I tried today and got a message on the pin pad something like "purchase could not complete" and it spat back an error code on the receipt printer. Viewing my account activity I don't even have an authorization from Sam's, so I am not sure if their POS system is blocking the purchase of GCs with Visas? I know I can order one online but I'd rather not wait for delivery.
